There's no *guarantee* that any *other* guessing or discovery mechanism that comes built into any general-distribution MUA will be correct, either. (Says the man who has to seriously beat even current versions of *Thunderbird* into accepting a manually-entered config and act as a test tool against the IMAPS servers we purpose-built and run for the appliances in the field. "How dare you NOT have an SMTP-out server for this account at all!" etc..) Regards, -- Jochen Bern Systemingenieur Binect GmbH
